Hi! Welcome to my homepage. I’m Siran Dai (戴思然), a fourth-year Ph.D. student at the Institute of Information Engineering, Chinese Academy of Sciences (IIE, CAS), supervised by Qingming Huang (黄庆明) (Professor at UCAS; IEEE Fellow) and Qianqian Xu (许倩倩) (Professor at ICT, CAS). I received a B.E. in Robotics Engineering from BJUT in 2022. My research interests include Self-supervised Learning and Information Theory.
